Superheat needs the full coal a bar normally takes, where the blast furnace halves it — compare the same bar under smelting. What Superheat buys instead is no furnace trip and 53 Magic experience a cast, which is the usual reason to do it. The experience below is that Magic experience; the Smithing experience for the bar comes on top.
